Some avocado toast is simple and fresh. This one is bigger, bolder, and built like a crave-worthy breakfast you would happily order out, then immediately want to make again at home.

This Crispy Prosciutto Chili Crunch Avocado Toast with Cheesy Egg has everything working at once: golden sourdough, creamy avocado, a jammy or fully cooked egg, sharp cheddar melted right on top, salty shards of baked prosciutto, fresh chives, flaky salt, cracked pepper, and a glossy drizzle of chili crunch.

It feels special, but it is still a one-slice recipe. No complicated prep. No long ingredient list. Just smart layering and a few small steps that make each bite crisp, creamy, spicy, salty, and rich.

Why this avocado toast works so well

The best toast recipes are all about contrast. This one has plenty.

The sourdough is toasted until golden, which gives it enough structure to hold the toppings without getting soggy. The avocado adds creamy richness, but it is balanced by sharp cheddar and smoky-salty prosciutto. The egg makes it hearty, while chili crunch adds heat, texture, and that savory oil that seeps into all the little cracks.

Baking the prosciutto is the small step that makes the recipe feel restaurant-level. It turns delicate slices into crisp, salty pieces that crumble beautifully over the toast. Instead of chewy prosciutto folded on top, you get a crunchy topping in every bite.

The chili crunch does double duty too. Heating a little with the avocado oil before adding the egg lets the oil pick up some of that garlicky, spicy flavor. Then a final drizzle on top brings everything together.

This recipe is ideal for:

A satisfying breakfast that still feels quick
A weekend brunch for one
A savory lunch when you want something more exciting than a sandwich
A single-serving meal that feels polished without much effort

Ingredients you will need

This recipe makes one loaded slice of avocado toast. It is easy to double, but cook the eggs one or two at a time for the best texture.

Ingredient	Amount
Prosciutto	2 slices
Sourdough bread	1 slice
Avocado oil	1 teaspoon
Chili crunch	1 teaspoon, plus more for serving
Large egg	1
Sharp cheddar cheese	1 slice

Chopped chives	To taste
Flaky sea salt	To taste
Fresh cracked black pepper	To taste

A few ingredient notes

Prosciutto

Thinly sliced prosciutto crisps beautifully in the oven. Keep the slices in a single layer so they bake evenly. They may look slightly soft when they first come out, but they firm up as they cool.

Sourdough bread

Sourdough gives this toast a sturdy base and a tangy flavor that works well with the creamy avocado and rich egg. A medium-thick slice is best. If the bread is too thin, it can crack under the toppings. If it is too thick, it can overpower the egg and avocado.

Chili crunch

Use a chili crunch you already enjoy, since its flavor carries through the whole dish. Some are more garlicky, some are sweeter, and some are very spicy. Start with 1 teaspoon in the pan, then add more at the end if you want extra heat.

Sharp cheddar cheese

Sharp cheddar adds a salty, tangy bite. It also melts nicely over the hot egg. White cheddar, yellow cheddar, or an aged cheddar all work.

Avocado

You only need 1/4 avocado for one toast. It should be ripe enough to mash easily, but not brown or watery. If the avocado is very firm, it will not spread smoothly.

How to make crispy prosciutto chili crunch avocado toast

This recipe moves quickly once the egg starts cooking, so prep the toppings first. Bake the prosciutto, mash the avocado, slice or ready the cheese, and have the chives and chili crunch nearby.

1. Crisp the prosciutto

Preheat the oven to 400°F.

Line a baking sheet with parchment paper and arrange the prosciutto in a single layer. Bake for 8 to 10 minutes, until it looks darker and slightly crisp around the edges.

Let it cool on the pan or on a plate. Once cooled, crumble it into pieces.

The cooling time matters. Hot prosciutto can still feel flexible right out of the oven. Give it a minute or two and it should crisp up.

2. Toast the sourdough

Toast the sourdough until golden and crisp. You can use a toaster, toaster oven, skillet, or oven.

For the best texture, aim for a slice that is crisp on the outside but still has a little chew in the center. That gives the toast structure without making it too hard to cut or bite.

3. Heat the chili crunch oil

Add 1 teaspoon avocado oil and 1 teaspoon chili crunch to a nonstick skillet over medium heat.

Let the chili crunch warm briefly in the oil. You do not need to fry it hard. A gentle sizzle is enough to flavor the oil and wake up the aromatics.

If your chili crunch has lots of solids, spoon some of the red oil into the pan along with a few crunchy bits. Too many solids can brown quickly, so keep the heat at medium.

4. Cook the egg

Crack the egg into the skillet. Cook until the whites are set and the yolk reaches your desired doneness.

For a runnier yolk, keep the heat moderate and remove the egg once the whites are opaque. For a firmer yolk, cook a little longer or cover the pan for part of the cooking time.

During the last 30 seconds of cooking, place the cheddar slice over the egg. Cover the pan to help the cheese melt.

The lid traps steam, which melts the cheese without overcooking the bottom of the egg. This is especially useful if you want a set white and soft yolk.

5. Build the toast

Spread the mashed avocado over the toasted sourdough.

Carefully place the cheesy egg on top. A thin spatula works best here, especially if the cheese has melted down the sides of the egg.

Sprinkle the crispy prosciutto over the egg, then finish with chopped chives, flaky sea salt, fresh cracked black pepper, and an extra drizzle of chili crunch.

Serve right away while the toast is crisp, the cheese is melted, and the prosciutto still has its crunch.

Tips for the best texture and flavor

A recipe this simple depends on timing and small details. These tips help keep the toast crisp and balanced.

Keep the toast sturdy

Avocado toast can turn soft if the bread is lightly warmed instead of truly toasted. Let the sourdough get golden before adding the avocado. A firmer base holds up better under the egg and toppings.

Do not over-salt too early

Prosciutto, cheddar, chili crunch, and flaky sea salt all bring salt. Add the flaky salt at the end, and use a light hand. You can always add more after the first bite.

Mash the avocado simply

You do not need a full guacamole situation here. Just mash the avocado with a fork until spreadable. The other toppings carry plenty of flavor.

If you want a brighter avocado layer, add a tiny squeeze of lemon juice. Keep it light so it does not compete with the chili crunch and cheddar.

Watch the chili crunch in the pan

Chili crunch can brown if the heat is too high, especially if it contains garlic or shallots. Medium heat is enough. If the pan starts smoking or the bits darken too fast, lower the heat before adding the egg.

Melt the cheese with steam

Covering the pan is the easiest way to melt the cheddar without flipping the egg. If your cheddar slice is thick, tear it into smaller pieces so it melts faster and more evenly.

Easy variations

This toast is flexible. Keep the same method and adjust the toppings based on what you have.

Make it extra spicy

Add more chili crunch at the end, or sprinkle on crushed red pepper. You can also use pepper jack instead of cheddar for another layer of heat.

Make it less spicy

Use less chili crunch in the pan and finish with a tiny drizzle instead of a full spoonful. The prosciutto and cheddar will still give the toast plenty of flavor.

Swap the cheese

Sharp cheddar is bold and classic, but these work too:

Monterey Jack for a milder melt
Gruyère for a nutty flavor
Havarti for a creamy finish
Swiss for a slightly sweet, mellow bite

Try a different bread

Sourdough is the top choice, but you can use country bread, seeded bread, or a thick slice of whole grain toast. The main goal is strength. Soft sandwich bread is more likely to collapse under the toppings.

Add greens

A small handful of arugula under the egg adds peppery freshness. Baby spinach works too, especially if you want a milder green.

What to serve with it

This toast is rich enough to stand on its own, especially with the egg and cheese. If you want to round it out, keep the sides simple.

Good pairings include:

Fresh berries or sliced citrus
A small green salad with lemon vinaigrette
Roasted breakfast potatoes
Iced coffee or hot coffee
Sparkling water with lemon

For brunch, serve it with a fruit salad and a simple drink. The toast already has fat, salt, heat, and richness, so fresh sides work best.

Make-ahead and storage notes

This recipe is best served immediately, but you can prep a few parts ahead.

The crispy prosciutto can be baked earlier in the day. Let it cool fully, then store it loosely covered at room temperature if using soon. If it softens, warm it briefly in the oven to crisp it back up.

The chives can be chopped in advance and kept in the refrigerator.

The avocado is best mashed right before serving. It browns once exposed to air, and the texture is freshest when just prepared.

The egg should be cooked right before eating. Reheated eggs can turn rubbery, and the cheese loses that freshly melted texture.

If you are making multiple servings, bake the prosciutto all at once and toast the bread in batches. Then cook the eggs to order.
